Name:
1) Put the following metric prefixes in order from largest to smallest
Kilo, centi, hector, mega, pico, milli, nano, deci, micro, deka
Mega,Kilo,Hecto,Deka,deci, centi, milli,micro,nano,pico
2) Convert the following:
a) 34.5 mm = ______________m (.0345)
b) 6,800 mg = __________________kg (.0068)
c) 3.22 x 10 4 mL = ______________L(32.2)
3) If you hit the bull’s eye 3 times are you accurate? Are you precise?(Both precise and accurate)
4) What are the steps of the scientific method?
1) State the problem
5) Collect and record data
2) Gather Information
6) Conclusion
3) Hypothesis
4) Experiment
5) Design a valid experiment( control and experimental set up) for testing a Tide® versus a
Chlorox® pen for getting out stains.
Independent variable – type of pen
Dependent variable- amount of stain that was removed
Control set up- use just water
Experimental- use the pen
Keep constant: the type of stain, the material, temperature of water, time of exposure to pen
and water when cleaning
Quantitative data- must measure the stain
Qualitative data- visual description of the stain
6) The speed of light is 3 x 10 8 m/s. Convert that into mph. ( 7 x 10 8 mph)
7) Mount Everest is 8848 m above sea level. How many miles high is that? ( 1km = .621 miles)
(5.494 miles)
8) The circumference of the Earth is 24, 901 miles around. How many days would a trip around
the world take in a car that is traveling 80.00 km per hour? ( Car travels at 49.68 mph and it
would take 501.2 days)
9) Calculate the following and put the answer in scientific notation with the correct unit and
significant digits:
a) 12.4 x 10 9m2 / 4.8 x10 3m =( 2.6 x 10 6 m)
b) (4.25 x 10 6cm) (3.23 x 10 -2cm) = (1.37 x 10 9 cm2)
c) 3.99 x 105 g + 4.88 x 10 4 g = ( 4.48 x 10 5 g)
d) 89,324 g- 456 mg = _____________________ g ( 89,324 g)
e) 45 cm + 23 m + 30 mm = _____________________ mm ( 23,480mm)
Extra Credit:
On average the Environmental Lapse Rate states that for every km of movement in the
atmosphere the temperature will change 6.5 oC. What is the temperature at 37,000 feet if at sea
level the temperature is 25 oC? ( 1 mile = 5280 feet, 1km = .621 miles)
( - 48 oC)
